**82C566/7/8     Viper-Max Chipset Scalable MultiMedia PC Solution   ?
***Info:
Overview

The OPTi  Viper-MAX Chipset provides a highly  integrated solution for
fully compatible, high performance  PC/AT platforms based on the Intel
3.3V  Pentium  Processor, Cyrix  6x86  Processor,  and  AMD K86  Proc-
essor. As the latest member of the Desktop Viper Chipset Family, it is
designed  from its  inception to  be the  highest  performance Pentium
chipset ever.   its feature set can  be scaled to  address entry level
UMA-based system  to high-end non-UMA work stations  and servers.  The
deep  buffers in  the Viper-MAX  minimize system  level  latencies and
maximize through-puts to both DRAM and PCI subsystems.

The chipset  provides 64-bit core  logic, with Unified  Memory Archit-
ecture  (UMA), and  integrated PCI  support, plus  sophisticated power
management  features.  This  highly integrated  approach  supplies the
foundation  for a  cost effective  platform without  compromising per-
formance. Its  feature set  furnishes an array  of control  and status
monitoring options  that are accessed  through a simple  and straight-
forward interface.  All major BIOS vendors  provide extensive software
hooks  that allow  system  designers to  integrate  their own  special
features with minimal effort.

82C566 Data Buffer Controller
The 82C566 performs  the task of buffering the CPU  to the DRAM memory
data path.

o   CPU to memory data buffer
o   CPU to PCI local bus buffer
o   Memory to PCI local bus buffer
o   208-pin PQFP

82C567 System Controller
The 82C567 provides the control  functions for the host CPU interface,
the  64-bit Level-2  (L2)  cache, the  64-bit  DRAM bus,  and the  PCI
interface. The 82C567 controls the  data flow between the CPU bus, the
DRAM bus, the local buses, and the 8/16-bit ISA bus. It interprets and
translates cycles from the CPU, PCI bus master, ISA master, and DMA to
the host  memory, PCI bus slave,  or ISA bus devices.  The 82C567 also
serves  as the UMA  (Unified Memory  Architecture) and  USB (Universal
Serial Bus) protocol interface.

o   3.3V CPU interface
o   DRAM controller
o   L1/L2 cache controller
o   UMA arbiter
o   USB interface
o   PCI interface
o   Arbitration logic
o   Data bus buffer control (memory data bus to and from host data 
    bus)
o   208-pin PQFP

82C568 Integrated Peripherals Controller
The 820568 contains the ISA bus controller and includes an 82C206, RTC
interface, DMA controller, serial interrupt controller and distributed
DMA. It also has a sophisticated system power management unit.

o   ISA bus controller
o   Master mode IDE
o   Type F DMA support
o   Integrated 82C206 IPC
o   System power management functions
o   PCI local bus interface
o   PCI to ISA expansion bridge
o   Serial interrupt controller
o   Distributed DMA
o   Keyboard emulation of A20M# and CPU warm reset
o   Port B and Port 092h Register
o   208-pin POFP
